From looking at this post, as an outsider, personally someone can charge whatever for a book, its up to the people wanting it how much they are willing to pay, if its poor then obviously people won't buy.... Please don't let any personal issues get into this post as its seems genuine enough...Any fieldsports related books are great for us, its not exactly a mega profitable adventure for an author unless hes the next jk rowling of the uk dog scene...
Hats of for writing a book, if its good, I hope you do well
